The Washington Animal Disease Diagnostic Laboratory (WADDL) collaborates closely with state and federal agencies in surveillance and testing efforts against Chronic Wasting Disease.
As a leading animal disease diagnostic laboratory, WADDL serves as the primary CWD testing laboratory for Washington, California, and some tribal organizations, playing a pivotal role in the wildlife health monitoring efforts in the Pacific Northwest.
WADDL employs two advanced diagnostic methods to test for CWD: the Enzyme-Linked Immunosorbent Assay (ELISA) for initial screening and Immunohistochemistry (IHC) for confirmatory testing.
